linux shell脚本检测目录下的文件是否有更新

检测文件个数可以修改，打印输出可以分别修改，检测间隔可以修改

只检测一个文件

file_path0=$(cd $(dirname $0); pwd)
file_path1=${file_path0}/hardware.prom
file_path2=${file_path0}/process.prom
file_path3=${file_path0}/cdn_code.prom
file_path4=${file_path0}/cdn_base.prom
function whether_changed(){
    file_old_stat1="`stat ${file_path1}|grep Modify`"
	file_old_stat2="`stat ${file_path2}|grep Modify`"
	file_old_stat3="`stat ${file_path3}|grep Modify`"
	file_old_stat4="`stat ${file_path4}|grep Modify`"
    while [[ true ]]; do
        sleep 2s
        if [ -f "$file_path1" ]; then
            file_new_stat1="`stat ${file_path1}|grep Modify`"
            if [[ `echo ${file_old_stat1}` == `echo ${file_new_stat1}` ]]; then
                echo "### In ${check_time}s ,${file_path1} does not change ###"
            else
                echo ${file_new_stat1}
                echo ${file_old_stat1}
                file_old_stat1=${file_new_stat1}
                echo "file hardware.prom change"
                # $2 2>&1 >/dev/null &
            fi
        else
           echo "file hardware.prom no exit "
        fi

检测四个文件，变化输出1，不变化输出0

文件格式如下，jiance.py是脚本文件，其他四个是待检测文件
